What is a snap switch also known as Snap Disc or snap action thermostat? Snap Disc, or snap switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that âsnapsâ from a convex to a concave shape at a set temperature. When the disc âsnapsâ, it either completes or interrupts a circuit.
Nowadays, however, the equipment is much easier to set up initially, and connecting all kinds of devices (from printers and Wi-Fi Cameras to other access points and routers) is a snap because of something called Wi-Fi Protected Setup (WPS). With WPS, itâs really easy to add devices on the fly. Many Wi-Fi connectable devices have WPS buttons on them these days, as do most D-Link routers. To see if yours does, just look for an icon featuring two opposite-facing arrows (see image on right).
