APEM’s HS series is available with a choice of eight handle options including traditional “castle” and “conical” styles, as well as a pushbutton option. Featuring a miniature tactile switch protected under an elastomer boot, the new pushbutton handle provides an off-momentary validation feature. The new pushbutton handle is noted as the option 6 handle in the Option Selection guide, as shown on this slide. When the option 6 handle is configured with a 4-way limiter plate, the HS Series provides five independent MOM-OFF-MOM operations.
