The HW series of 22-mm switches and pilot lights and SJ/SU series of relay sockets have been upgraded with options for push-in wiring technology. The panel-mount pilot devices feature six-color illumination with a single high-visibility LED. SJ/SU relay sockets are available with accessories and many form factors. Adding push-in wiring connections gives users extra design options and helps to provide safer, more reliable installation. Ferrules and stripped solid wires can be connected by 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.
