Tilt switches are used to sense movement (tilt) of a device above and below a horizontal axis. The angle through which the switch must move for proper operation – the differential angle – is measured from the point of just make to just break; it is specified as a maximum. Some applications include: thermostats, level controls, appliances, security alarm systems, toys and games, float switches and water-treatment equipment (non-mercury)
Tip-over switches sense tilt over 360° of a vertical axis. A common use is in portable heaters used in the home to prevent electrical shock or fire. When the heater tilts more than a specified angle, the switch operates turning the heater off. This angle, called the operating angle, describes the angle from vertical to the point of contact operation. Both normally closed (tilt to open) and normally open (tilt to close) switches are available. Some additional applications include: portable lamps, PC anti-theft devices, vending-machine alarms and machinery security systems
Different technologies are available.
Tilt switch: Ball contact, Opto-electronics, Electronic tilt, Micro miniature, Non mercury contacts, Surface mount
Tip over switch: Ball contact

The IRIS Tilt Switch and Controller is a powerful control device that enables you to measure and respond to rotational movements in any direction with reference to the unchanging gravity vector. Standard versions of IRIS offer 5 user-programmable thresholds and hysteresis settings. Threshold checking rate also is user-selectable, as are powerful functions such as autozero, data smoothing, and data format selection. In addition, IRIS is a full-featured biaxial inclinometer available with RS232 or RS422 output for easy deployment in a variety of applications. Typical applications include platform level control, avoiding tip-over conditions, and control of solar trackers.

Tilt switches are used to sense movement (tilt) of a device above and below a horizontal axis. A typical use is in a thermostat. A glass mercury switch is mounted to a bi-metallic spring which expands and contracts with temperature. As the spring moves, the switch contacts pass through the horizontal plane, opening or closing to operate the furnace or boiler. The angle through which the switch must move for proper operation
– the differential angle – is measured from the point of just make to just break; it is specified as a maximum. When selecting a tilt switch, it is important to ensure that the operating mechanism can move the switch through an angle greater than the differential angle. Some additional applications include: level controls, appliances, security alarm systems, toys and games, float switches and water-treatment equipment (non-mercury) .

General description :
Photo interrupter, rather than contacts, ensures high reliability.
Sealed construction for protection from environmental elements, including hydrogen sulfide, sulfur dioxide, and nitrogen hydroxide. Terminals are made of ammonia-resistant materials.
Totally sealed body allows process compatibility for time-and money-saving automatic soldering and cleaning.
Space-saving compact dimensions allow high density mounting.
Internal steel ball movement allows functionality of 360° circumference rotation.
The DSB series switch is well-suited to meet product safety concerns due to normally closed (on) status.
Crimped terminals ensure secure mounting and prevent dislodging during wave soldering.
The switch is triggered when tilted beyond ±30° of the horizontal.
