PIT ES100 Emergency Stop Pushbutton The PITestop emergency stop pushbutton is suitable for applications up to category 4 in accordance with EN 954-1. It also meets the requirements of IEC/EN 60947-5-5 / EN 418, UL 508, CSA C22.2 No. 14. A special safety contact block prevents contact elements being released without detection. With its yellow border, the contact block is easily recognisable as a safety element. Together with the contact elements it forms a fixed unit, so it cannot be wrongly configured, nor can individual contact elements be attached incorrectly. |  |
