Interlock Switch Style
|
|
|
| |
Your choices are...
|
|
|
| |
Keyed or Tongue Style Interlock Switch
|
|
Interlocks where the switching element and the actuator do not form a design unit but are functionally combined or separated during actuation. Interlock switches of this type are Category 2 devices.
|
| |
Hinge Operated Style Interlock Switch
|
|
Device is mounted over the hinge pin of a hinged guard. The opening of the guard is transmitted by the positive mode operation of the mechanism to the control circuit. Interlock switches of this type are Category 1 devices.
|
| |
Manually Operated (Bolt) Interlock Switch
|
|
Bolt must be manually retracted, providing time delay for machine run down. The bolt locks the guard in place and also operates the contacts. The first few turns of the bolt open the contacts but the locking bolt is not fully retracted until the knob is turned many more times.

Solenoid Latching (Guard Interlock)
|
|
Safety interlock device with solenoid latching to provide interlocking of the hazard power source with guard movement and also to prevent opening of the guard until it is safe to do so. They act in conjunction with the control to keep moveable safety guards in their safety position until dangerous conditions no longer exist.
