Push-In connector switches halve assembly time, says Foremost
Up to 55 per cent assembly time can be saved using Push-in connection technology, says Foremost Electronics. The connectors also provide a high conductor retention force and are capable of handling multiple conductor types.
Foremost Electronics offers a range of 22mm control panel switches from IDEC with secure screw-less push-in terminations to reduce assembly time.
The Push-In termination technology is typically used in control panel and machine building applications. It is available on the industry standard YW and HW series and the CW series (flush mounting) switches. Each of these three series of switches are for 22mm mounting and available as a push button (with and without illumination), selector switch, key selector switch and pilot light/indicators.
The cost-effective YW series (22 mm industrial switch family) delivers key features required by the industrial automation market including push button, illuminated push button, key and selector switch.
The CW series (22mm flush design, industrial switch) is specified where the style of a product is important, says Foremost. It is used in medical appliances, consumer applications and the food industry, where aesthetics and reliability are the key to success.
The HW series (22mm industrial switch) is IDEC’s largest portfolio of switches and actuators for the industrial automation market and includes rotary switches, selector switches, combined rotary and push-button, four- or five- position selectors.
Wire termination technology has slowly migrated from a screw connector to “screw-less” terminations; first on DIN rail terminals and then on PLCs and relay sockets. Initially, a spring clamp was used but this requires a screwdriver to open the spring to allow the cable to be inserted. More recently, the spring clamp has been replaced with the push-in termination. At IDEC, this simple, safe method of connectivity is referred to as the S3 termination.
With the Push-In connection technology, the force on the conductor is generated by a pressure spring made of high quality stainless steel. The spring sits in a cage and is automatically opened upon connection and only released when a release tool is used.
