TH-800 Series Single-Point Level Switches incorporate level monitoring and a temperature switch in a single unit. A single-setting temperature sensor is in the bottom of the stem. TH-800 are ideal for use in oils and water and are intermediate in size.
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.
