Heavy-duty limit switch

Bhartia Cutler-Hammer manufactures heavy-duty limit switches suitable for working in highly contaminated atmospheres and extremely high shock and vibration conditions. Type L limit switches are available with a variety of operating heads to meet diverse applications: Rotary lever operating heads, which are of the spring return variety, with rotary shafts, operate clockwise, counter clockwise or in both directions. Operating levers may be rotated (360 degree) and locked on the rotary shaft in any one position. The levers are provided with 19 mm diameter metal rollers. Two types of roller lever operators, with fixed length of 38 and 76.2 mm, are available. The third type has an adjustable length between 32 and 82.5 mm. Top push operating heads are available in two designs. One has an adjustable push button, the length of which can be adjusted up to 8 mm. The second type has a metal roller of 11.1 mm diameter. Side push operating head is also available with an adjustable push button. This type of head is designed for small space and low travel application where the actuator travel is perpendicular to the switch. Cat whisker operating head (nylon and steel rod) has been designed for applications where extremely low operating force is available. The operator consists of a nylon covered wire/steel rod, which is a spring return switch. The contact mechanism is enclosed in a phenolic moulding with a transparent thermoplastic front cover. The complete unit can be removed and released without the risk of changing the operating characteristic of the limit switch. Important features of the switch include `Set-back? head design, completely oil tight, watertight and dust proof design and terminal with ample wiring space.
