IDEC switches and relays with push-in contacts

IDEC Corporation has enhanced its HW series of 22 mm switches and pilot lights, as well as the SJ/SU series of relay sockets, with options for push-in wiring technology.

Ferrules and stripped solid wires can be connected by simply pushing them in, without the need for any tools. There are no screws to torque or tighten. Wires can be removed by pushing down a small orange release pin with a screwdriver. Wiring can be performed by workers of any skill level, and wiring time is reduced by about 55% compared with conventional screw terminal connections.

Constant spring-loaded tension on the wire maintains a reliable connection and improves vibration resistance. The entire push-in structure is designed as finger-safe so workers never touch the conductors.

Push-in contact blocks are compact, taking less depth than traditional versions. This improves working space inside a panel and potentially enables enclosures to be downsized. Connections are angled to facilitate wire entry, and the contact blocks feature a handy test point for insertion of a multimeter probe. Both switch contact block and relay socket electrical connections are rated IP20 finger-safe. All other panel design considerations, product functions, features and ratings remain at the same high level of quality and performance.
