Snap Action, Limit Switches - D4SL-N4PFG-DN Application Field and Working Principle

Snap action, limit switches, a type of discrete switch, are commonly used for sensing physical parameters and for control circuits. Snap action limit switches feature a short, rigid lever arm, which returns to its original position when subjected to an external force. The D4SL-N4PFG-DN is a type of snap action, limit switch that is used in numerous applications in both industrial and commercial settings. This article will discuss the application field and working principle of this reliable and useful switch.

The D4SL-N4PFG-DN is a cost effective and reliable limit switch that is used in numerous applications such as industrial machinery, automation, robotics and other control systems. It is commonly used to actuate mechanical and electrical components in an automated system and can be actuated by pressing, twisting, pushing or rotating the switch’s actuator. The actuator arm is made of stainless steel, and the switch is sealed in a rugged housing to withstand harsh environmental conditions. The switch is available in a variety of mounting styles such as panel mount, through-hole mount, DIN rail mount, and surface mount.

The D4SL-N4PFG-DN is a single pole, single throw (SPST) momentary action switch that can be activated by the user when pressure is applied to the switch’s actuator. The switch is biased to its normally open position when not actuated. When the actuator is depressed, the switch’s contacts close, resulting in an electrical connection. When the actuator is released, the switch returns to its normally open position. The switch is available in two contact forms: make and break, and make and stay. The make and break form allows the contacts to stay closed after being actuated, while the make and stay form allows the contacts to immediately return to their normally open position after the user releases the actuator.

The D4SL-N4PFG-DN is capable of handling up to 4A at 250VAC, and it is highly resistant to water and dust, making it ideal for harsh environments. The switch also has a mechanical actuator life of 1 million cycles and electrical life of 500,000 cycles. The switch is rated for an operating temperature range of -25°C to +85°C, and is rated for a high shock force of up to 40G.

The D4SL-N4PFG-DN snap action, limit switch is a reliable switch option for numerous applications. Its rugged design and reliable performance make it an ideal choice for a variety of control and automation systems. The switch’s varying actuator styles and contact forms allow the switch to be used in a wide range of applications and conditions.
