Honeywell MICRO SWITCH™ Sealed and High Accuracy Switches
Engineered smarter. Basically better. Honeywell offers environmentally sealed limit switches and basic switches and toggle switches, as well as hermetically sealed products. Many of our environmentally sealed limit switches incorporate MICRO SWITCH™ SM/SX series components — resulting in enhanced accuracy and reliability under most extreme conditions.
The hermetically sealed lineup includes switches that maintain the contact in a gas-tight seal, while transmitting force and motion to the mechanism through a metal diaphragm. And our high-temperature products have the switching element mounted on a ceramic base with stainless steel enclosures.
Honeywell S&C's flexible sealed switch line opens the door to new, powerful possibilities for your applications.

A switch design that combines gold crossbar contacts with an all-in-one-welded contact terminal construction that delivers reliability and extended life in harsh low-pressure environments. The MAM005 line of ultra-low pressure, vacuum, and differential switches can be ordered preconfigured for immediate shipment, as a standard product tailored to user needs, or custom-designed for special applications. The switches come configured with different port orientations to fit mounting requirements and come in nine different diaphragm materials. The devices can be selected to assure chemical compatibility with most mediums and reliable operation at temperature extremes.

Furnace & Water Heater Air Proving Switch
The Mamco / Lefoo LF-31 series switch was designed for the HVAC industry where safety and reliability are essential. This series has also proven to be a viable solution for many pneumatic OEM applications.
Available in vacuum, differential and pressure models, with fine silver or gold cross bar contacts. The LF-31 is capable of detecting pressures, as low as, .05" of water. Factory calibrated units maintain set point tolerances of +/- 10% over a temperature range of -40º F to 185º F due to it's molded silicone diaphragm and the stability of it's glass filled polyester body.
MAMCO offers multiple electrical terminations and mounting options, as well as, bleed holes and three different size orifices. This switch series is not only the leading product in the market offering the highest quality and reliability but is also the most economical.

MAMCO/LEFOO LF-20 PRESSURE SWITCH
Because of its special internal design this switch can tolerate high pressure spikes inherent on many pressure systems. The switch is factory calibrated but in the case that adjustment is needed in the field the switch offers an adjustment screw to facilitate any fine tuning required. The standard diaphragm employed by Mamco is polyimide (Kapton) making it compatible with many gases and liquids. Several other diaphragm materials are available that make the switch compatible with many mediums. Various electrical terminations are available including ¼ tabs and a metric-pack connector that forms a tight seal when connected.
Because of their ruggedness the Mamco LF-20 is a popular choice for the many OEM applications.

Anyone who uses ultra-low pressure, vacuum and differential switches can tell you that they will inevitably wear down in low pressure environments, causing contact erosion, loose terminals, switch instability and leakage.
The result? Equipment failure, downtime, and productivity setbacks no busy manufacturer can afford. Fortunately, now there's an alternative-
New Solution to Ultra Low Pressure Switch Problems Helps Avoid Leakage, Set Point Instability and Contact Resistance- an innovation in switch design that combines special gold crossbar contacts with a revolutionary "all-in-one-weld" contact/terminal construction for switches that deliver reliability, long life in harsh, low pressure environments—the MAM005 line of ultra-low pressure, vacuum and differential switches.
Most important, not only do these rugged and dependable switches last longer, they're comparatively priced, no matter if you're just looking for pre-configured switches available for immediate shipping, standard switches tailored to your business needs, or custom-designed switches for special applications

Model: LFS 03
Electircal Function: 1 pole NO, 1 Pole NC
Temperature: Ambient:-10 to +85
Electrical Connections: Tab terminals 6.4 X0.8 mm, Tab Terminals 4.8 x 0.8 mm (1 pole NO only)
Pressure Range: Pressure: +15 to+2500mbar
Tolerance:+/- 10% NO; +/- 15% NC
Vacuum: -600 to -15mbar
Tolerance: +/- 15%
Simple Line Connections: Pressure and Vacuum: Inlet 4.0 or 5.5 mm(up to 500mbar) Threaded inlet M10x1mm or 1/4 gas.
Almost no hysteresis
Medium: Non hazardous gas only
Contact carrying parts: Brass Silver plated (gold on request)
Membrane: Nitrile, EPDM, (Silicone, Perbunan on request)
If two points are required, two pressure switches with different calibrations should be employed. The method of fixing the tab terminals to the switch body does not allow for absolute air sealing. The switch is therefore not reccommended for applications where static vacuum has to be maintained. However, special models with additional pressure spring that allow for the vacuum to be connected to the pressure inlet side are available on request.

# The VSP Power Supply series utilizes modern switch mode technology to produce high-power, low-noise switching supplies that cost around twenty five percent less than linear supplies with the same power. The VSP series offers as much as 1.2 kilowatts in a 19 inch rack mountable chassis that measures just 1U (1.75 inches) in height. The VSP series power supplies can provide precise output voltage control via manual tuning utilizing front panel mounted ten-turn potentiometers or by remote control from an RS 232 interface (provided on standard VSP models) or by GPIB interface (add "GPIB" to the model number for a VSP with GPIB interface instead of RS 232). All models have remote sensing capabilities to automatically maintain desired voltage levels at the load. Provides 1.2 kilowatts at 20V, 40V, 60V and 120V output voltages (output voltages vary between different models)
# Compact 1U (1.75 in by 19 inch rack mountable chassis) is just a home on a bench as it is in a Rack
# Up to nine units can be cascaded, producing more than 10 kilowatts of DC power
# Front-to-back air flow allows full power operation without space between supplies
# Output on/off switch on front of unit
# RS 232 interface

The B+K 1692 Switching Mode DC Power Supply provides high current output in a lightweight and compact package. It is suitable for a variety of uses, especially for powering DC operated mobile radio equipment on the bench. It provides a variable voltage output from 3V to 15V at 40A continuous operation. In addition a fixed 13.8 VDC output is also selectable by a slider switch. Switching mode power supplies have the advantage of lightweight and high efficiency when compared to traditional linear mode power supplies. The efficiency can exceed 80% under the best conditions. Advanced circuitry protects against overload and provides immunity from RFI. A bright red and green LED display provides for an accurate and highly readable indicator of settings.
