Relays are still a good solution in some situations. When you’re dealing with high power, or when you need something exactly electrically identical to a closed switch, relays are a reasonable ...

[Paulo Borges] has created something quite different, however, with his in-the-wall servo-controlled light switch. This build forgoes the need of any relay to switch mains power, and because it ...

it relays them from the switch's input port to the output port, hence the name. Attachment to a frame relay network is made via a FRAD on the customer's premises, which may be a separate device or ...

Pickering Electronics has introduced a new 20kV addition to its established high-voltage Series 63 range. This latest addition sets a new industry standard by providing a 20kV stand-off across the ...

Menlo Micro has released another MEMS electro-mechanical relay, this time a single-pole four-throw (SP4T) dc-18GHz switch. MM5120 will handle 25W (150W pulsed), according to the company, though its ...
