Ribbon switches are made of a special PVC sheath in which is housed the sensor element, which provides an electrical signal when any external crushing action is exerted on the board. A profile of aluminum plate completes the device for its attachment to the machine. These devices are designed to prevent injury to personnel against crushing by moving parts as sliding doors, gates, elevators plans etc. detecting an electrical contact via a control circuit.
These ribbon switches are a continuous NO contact. The safety 4 wire ribbon in combination with PS3 control module can reach the CAT 3 - PL “e” as indicated in the ISO 13849-1 standard.
