Single-Point Level Switch LS Series

Single-Point Level Switch LS Series

Single-Point Level Switch LS Series

The durable construction of these switch designs ensures long, trouble-free service. Because the effects of shock, wear and vibration are minimised, these hermetically sealed switches provide precise repeatability with no more than 1% deviation. The switch actuation points remain constant over the life of the unit. Ideal for shallow tanks or restricted spaces, or for any low-cost, high volume use.
