These safety switches feature compact, reinforced thermoplastic bodied designs, suitable for applications on very small machines, typically as used with packaging systems. Designated as the NQ and TQ series, these products can fit in spaces where it would be impractical to install other guard locking solutions. The TQ switch has a body size of 75mm square x 15mm thick. It incorporates five internal switching contacts with optional locking mechanisms of guards locked or released by spring force when used in conjunction with the internal energised solenoid. The switch incorporates a status condition LED, and accommodates a vertical actuator approach and mechanical key release of guard locking with a three directional approach. Where guard locking is not anticipated, the smaller NQ series safety switch can be used. This has a body size of 78x30x15mm and three internal switching contacts are provided.
