Limit switches are available in different models: precision, small precision, compact and micro. Various switch housings are offered for different environments.
Simple operator styles such as button, roller and lever types afford versatility in the specific application. Limit switches can come in normally on (NOI) and normally closed (NCI) positions.
Some limit switches are available with conduit entry. Others are made triple-sealed for wash-down or hydraulic applications. Others are made with die-cast metal housings for heavy-duty uses in rugged environments.
Limit switches are reliable, rugged and easy to install in a variety of applications and environments. Parts such as levers and buttons are easy and inexpensive to replace and maintain.
Engineers and electricians must know about these simple devices. Construction workers, maintenance mechanics and purchasing agents can also benefit from a basic education in how these devices function.
