Jai Precision Limit Switches are designed for industrial duty applications. They are small in size, reliable in operation, have exceptionally long life and are accurate. The wide variety of switch operating mechanisms coupled with the choice of either single pole 1NO + 1NC or double pole 2NO+2NC changeover contacts permit easy selection and application for many needs.
The contact mechanism incorporates a moveable contact assembly utilising two pressed leap springs to provide quick-make, quick-break action which eliminates any position of zero contact pressure and ensures non-teasing action, even with an extremely slow operation motion.
The light weight berrylium-copper contact carrier with large faced silver contacts and low bounce mechanisms assure long life on high load applications. The serrated silver stationery contacts, definite wiping action and high contact pressure assure reliability on dry circuit applications. The switch is completely enclosed in a semi dust-tight moulded, phenolic case of great physical strength and high arc-resisting capacity. weight berrylium-copper contact carrier with large faced silver
A wide variety of operations is available for use in combination with the basic switch. These operators with individual mounting variations, afford a high degree of versatility.
Push button plunger
These are designed for one hole panel mounting. The plunger mechanisms is of oil-tight construction and prevents any ingress of oil, including coolant. These operators are designed for an inline actuating motion with controlled over-travel.
Operators are designed for one hole mounting and are of oil-tight construction. The roller plunger comes assembled either in line with the length of the contact block or at right angles to it. This allows the roller to accept cam or slide operation from any of the four directions.
Six inch (150 mm) lever
Operators provide either top and right hand mounting or top and left hand mounting. With this do-it-yourself operator, the lever may be formed by the user to satisfy unusual requirements and can be cut or bent to any desired length or shape.
Operators are available with either top and right hand mounting or top and left hand mounting and are equipped-with a steel roller which may be operated by a cam or some similar actuating device. Operation is provided in both directions.
