Technical description
The switch is in "ON" position with the red knob extended. Pushing the knob instantly opens the circuit and the permanent magnetic blowout ensures that inductive arcs are extinguished. Because of the built-in permanent magnetic blowout correct polarity of line termination is required. In case of electrical or mechanical damage of the switching element, it can be changed easily, which guarantees an extended life of the unit as well as cost effective maintanance. When fitted with the optional keyswitch, the S132 may be locked in the "OFF" position so as to prevent unauthorised use of any equipment.
Features
- Momentary action mechanism
- Magnetic blowout
- Two definite bistable positions
- Cylinder lock available
- Auxiliary contact available

The MP720 positive opening position switch is a dependent-action, changeover, double-gap, contact element, which is connected by means of a cable directly overmoulded into the housing.

It is assembled as an addition to a door latch
It avoids accidents related to the possible locking of an operator in a dangerous area.
It is equipped with a push button and safety contact block for the equipment emergency stop, the DEU adapts to all types of door latches and it is installed inside the protected area.
The emergency evacuation device forces ejection of the latch. The pushing the button frees the latch and stops the machine immediately due to a 2 0 safety contact and permits opening of the access by pushing the door.
EMERGENCY EVACUATION DEVICE
In case of emergency:
1 – The locked-in operator presses the push button.
2 – The latch separates from the DEU.
3 – The safety contact opens the emergency stop circuit.
To re-start, it will be necessary to unblock the latch after the installation is safe.
The latch must be assembled in the fixed part of the access.
Options
- Without contacts

Even redundant, secure emergency-stop chains are ineffective unless the contact block is accurately connected with the emergency-stop button. The patented safety contact blocks of Schlegel Elektrokontakt are the response to this danger that may occur e.g. due to a negligent assembly or a mechanical damage.
In such an emergency they ensure that the emergency function is activated and that the installation is immediately shutdown. It can only be started up again after trouble-shooting.
The contact blocks are available with screw connections or Faston terminals and do have positive opening contacts acc. to IEC60947-5-1. They can be supplied with one or two channels and also, once combined with the relative E-stop button, in a foolproof version acc. to EN60947-5-5 and EN418. The high-quality contact elements allow reliable switching even of low currents (5mA at 24V or less). They are available as conventional contact blocks as well as for the AS-Interface-Bus (Safety@Work).

The XA and XW series of Emergency Stop switches include a revolutionary new technology called "safe break action" that will change the way E-Stop switches are designed. This innovative concept provides greater levels of human safety and is the first of its kind in the world.
Conventional E-Stop switches are designed with spring pressure on the Normally Closed (NC) contacts, keeping them in the closed position and allowing the machine to operate. Improper installation or excessive force to the stop button in an emergency may break or dislodge a vital part, causing the spring loaded contact to stay closed. This situation renders the E-Stop incapable of stopping the machine and can lead to catastrophic events, personal injury and possible loss of life.

Pull-wire emergency stop switches are mounted on machines and sections of plants which cannot be protected by guards. In contrast to mushroom head Emergency Stop push buttons, on pull-wire switches the Emergency Stop command can be initiated from any point on the wire.
In combination with one of the AES and AZR range safety monitoring modules, see chapter 10.3, ZS range pull-wire emergency stop switches can be used for Control Category 3 or 4 to EN 954-1.
Design and mode of operation:
All of the pull-wire emergency stop switches conform to European Standard EN 418. They have a positive linkage between the NC contacts and the wire rope. The pull-wire emergency stop switches are brought into the operational condition by pre-tensioning the wire, i.e. the NC contacts are then closed and the NO contacts open.
Schmersal make both standard and AS-i Safety at Work pull-wire emergency stop switches.

Tubular handles with switch Emile MAURIN the tubular handles with switch were designed for unlocking/releasing of the safety devices of the sliding doors and the rotary/revolving doors. - Optimized Ergonomics (with the switch directly with the door) - Assembly and installation simplified - Functions additional possible directly on the handle and connected to the door: switch of stop urgently OFF, push-buttons START or RESET, luminous indicators All the switches, push-buttons and indicators, normally installed on external panels or rising, here are directly integrated on the tube of the handle. While unbolting the device with the inch, the same hand can open the door. According to your applications, various versions are deliverable with a switch of stop urgently OFF or 2 push-buttons being able to be used for example, one for START and the other for RESET. The version with 1 only push-button implies that it is about an element of contact. The 2 indicators are integrated in the case circuit breaker and they can post various operating conditions, allowing, for example, with the operator to make function or control its machine directly since the door. The second push-button can be used as element of contact. The tubular handles are out of aluminium stripped black chechmate or anodized. The side supports in zamac are stripped black chechmate. A kit with the caps of red, green and blue color is provided for each button.
