LS-7 Single-Point Level Switch With 5 Amp Relay

Part Number: 181291
LS-7_5AMP_247380
Image is of similar product

PRODUCT DESCRIPTION:

A single pole double throw relay enables this level switch to control two independent loads up to 5 amps each, switching N.O. for one load and N.C. for the other. This unit is designed to operate with a load connected to each of the two outputs. These loads must be 10 watts, minimum, for correct SPDT switching. One load used alone must be connected to the N.O. terminal. With this load, which may be less than 10 watts, the unit will operate the same as an SPST unit.

How do I wire part# 181291, model type LS-7 with 5 AMP relay?

Please see the wiring diagram below: Wire diagram for part 181291

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.
