Item # 04949-000, Palm Switch Guard/Actuator

List Price $269.10

The Palm Switch Guard / Actuator is designed to replace the ringguard on REES palm operated switches. It features sturdy zinc die castand steel, both are painted with dry powder paint. It has a large operatingpad which reduces the activation force on the center of the hand anddirectly on the ulnar artery and median nerve where they pass throughthe palm. There is less potential compression to the hand if the outerpart of the palm is used to depress the switch. A study by the ergonomicconsulting firm “Human Dynamics, Lancaster, OH,” found that bothresistance and travel play important roles in control design. Travelprovides the user with sense of movement and position. When associatedwith resistance, such movement provides tactile feedback about controlactivation.This feedback helps the operators perception and increasesaccuracy, safety and efficiency. Tactile feed back lets the operator knowthat the switch has been activated because they can ‘feel’ the switchworking. On switching devices without feedback operators tend to pushharder causing muscle fatigue and increasing the risk of injury. Also,a comfortable and lower trip force is created by the mechanicaladvantage of the actuator’s design.
