Safety Interlock Switches
Safety Interlock Switches are Switches that prevents gear shift lever from moving from park position until brake is applied.It is a switch designed for mounting on a door, drawer, or cover so that it opens automatically when the door or other part is opened.A safety interlock switch is a normally open valve that closes in the event of a process upset. Usually it is attached to electronics that perform logic operations on process conditions. Safety interlock switches are designed to work together with hinged, sliding, or lift-off guards and barriers. When the guard is opened, the power supply to the machine is disconnected.
Safety Interlocking Switches are designed for use in applications where the stopping time of the hazardous area is shorter than the access time of the operator opening the guard and reaching in. Recommended for applications with little or no shock or vibration, where there is minimal chance of the door or guard opening unintentionally.
The interlock safety switches are designed to provide position interlock detection for moving guards. The actuator is fitted to the moving part (frame) of the guard and is aligned to the switch entry aperture. The interlocking switches have rotary heads which provides ease of mounting and offer different actuator entry positions. Some of the switches can be locked in the protective position which prevents unwanted access to machinery until dangerous operations have ceased.All switches are robust and can withstand severe environments. Depending on the environment where the switch will be used, different material can be chosen.
