LS-1900TFE Series Single-Point Level Switch is an all plastic materials SPDT switch that resists build-up of foreign material or sticky media. Float travel remains uninhibited in viscous or corrosive liquids.
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.
LS-1900 Series Single-Point Level Switch are intermediate in size, are suitable for high viscosity liquids and provide excellent stability for general use in oils and water. With large float displacement, the LS-1900 Series switch withstands rough...
