The 3 stage foot switch BERNSTEIN, has excellent design and technology. The enable foot switch provides two enable contacts and one signalling contact and is available with or without latch. . If the pedal is pressed up to pressure, this renders both enable contacts to shut closed. If the pedal is then released, the enable contacts opens again. If the pedal is pressed up to the pressure point, the enable positive opening action contacts are then opened. For the application of an enable device, the rules DIN EN ISO 12100 and DIN EN 60204-1 apply. Allowing efficient and accurate results.
