Abstract

A switch actuator is molded integral with the control panel such that the face of the panel is free from protrusions. Cuts are made through the panel material on three sides to form one actuator section. A relief cut can be made on the fourth side. Force-concentrating blades are molded integrally to the actuator section for contact with an electrical switch. Depressing the actuator section causes the blade to depress and actuate the switch.

Panel Switch Actuator

A switch actuator is molded integral with the control panel such that the face of the panel is free from protrusions. Cuts are made through the panel material on three sides to form one actuator section. A relief cut can be made on the fourth side. Force-concentrating blades are molded integrally to the actuator section for contact with an electrical switch. Depressing the actuator section causes the blade to depress and actuate the switch.

An orthogonal view of the control panel 1 with the switch actuators 3 is shown in Fig. 1. Fig. 2 shows a cross-sectional view taken along lines 22 of Fig. 1. To form the actuator 3, cuts 4 are made along one dimension. A thickened section 6 can be molded into the control panel 1 to accentuate the actuators 3. The actuators 3 include force-concentrating blades 7 molded to the underside of the panel 1 (Fig. 2). The blade 7 contacts the plunger 8 of a switch 9.

A relief cut 10 can be made into the actuator 3 for ease of depression. The switch 9 and plunger 8 represent any type of a switching actuator, such as the printed circuit board-mounted switch, which could be made of a flexible spring contact and two extended pads formed in the printed circuit board.

In operation, finger pressure near the center of the thickened section 6 of the actuator 3 causes the actuator 3 to flex due to the cuts 4 and 5 and the relief cut
10. The flexing of the actuator 3 causes the force-concentrating blades 7 to depress the plu...
