Time Delay Control Switch Relay (TD-CSR) from Electroswitch provides a safe and effective means of mitigating arc flash danger in local circuit breaker operation by allowing for a manually initiated ...

Real switches and relays exhibit a finite resistance called “contact resistance,” which increases over time with the number of actuations. Furthermore, as a switch or relay changes state, the contacts ...

In this circuit the 555 timer is used in a novel way, as a voltage controlled switch.The old and omnipresent NE555 can be very good at something it was not meant for: driving relays or other loads up ...

When to use mechanical vs. solid-state devices. The parameters that should be considered when selecting a device. Optimize your selection for lowest cost/maximum ...
