PRODUCT DESCRIPTION:

This compact Side Mount Level Switch is optimized for calcifying hot water applications. The Drop Float design keeps critical sensor elements out of the water thus eliminating liming or mineral deposit problems that can affect other level switches. This switch is ideal for use on food warmers, hot water heaters, steam cookers and small boilers or wherever water evaporation occurs. Made of Noryl and WRC approved for use in potable water.

Is there a minimum current flow requirement for a standard 20VA reed switch?

Yes, very low currents (< 5ma) can prevent “cleaning” of the contacts or not have enough energy to maintain low contact resistance. 5ma is likely a good minimum for our standard 20 VA switch. But you also want enough voltage. Approximately, 5V, 5ma is a good minimum. For low current switching we recommend a 10 VA reed switch which can better handle lower loads. (1ma for example).

What is the life expectancy of a reed switch?

A reed switch is extremely rugged and designed to operate reliably for many years, under ideal conditions, up to about 2 million cycles. To achieve maximum service life, reed switches benefit from protected electrical supply.
