Description

The JHAK mushroom-head palm switch is a large actuator for operation by hand, foot or another suitable part of the body. The catalogue offers self-reset and pull-reset (self-locking) versions, with different operating forces and switching frequencies.

The catalogue describes pushbutton and emergency-stop applications. Red pull-reset models use a yellow-and-black enclosure; self-reset models in the selection table use a grey-and-black enclosure. Select the action and contact configuration for the ordered model.

IP65 protection, as specified in the catalogue.
Silver-alloy contacts; gold-plated contact options by request.
Red, green, yellow and black head-colour codes in the ordering guide.
Side cable entries: 3 × M20; bottom entry: 1 × M16.
OEM and customised configurations by enquiry.

The model-selection table prints the pull-reset model names without the /V segment shown in the ordering example. Specify the required reset action and confirm the complete order code with Jinhong. Contact-code mappings above reproduce the catalogue; available options cannot be freely combined.

Dimensions

All drawing dimensions are in mm. The dimensioned drawing below shows a 105.5mm overall-height callout, Ø95mm head diameter, 86.5mm / 69.5mm / 65mm mounting callouts, a 40mm bottom callout and a 5.5–6.5mm callout.

Variant confirmation: the catalogue parameter table separately lists W94 × H101 × L94mm. This differs from the dimensioned drawing. Confirm the dimensions and reset configuration of the ordered model before preparing mounting holes.

Wiring & Operation

The catalogue uses M for normally open (NO) and B for normally closed (NC). The diagrams show: KC11 with 4–3 NO and 2–1 NC; KC01 with 2–1 NC; and KC02 with both 4–3 and 2–1 NC. The terminal numbers and circuit symbols below are reproduced from the catalogue.

Operation and reset

Self-reset versions return after the actuator is released. Pull-reset versions latch and are reset by pulling the mushroom head upwards. The pull-reset illustration applies to the self-locking version.
