Compact size from rocker switch design
The new JC025 and JC030 single axis fingertip rockers from Penny and Giles Controls allow system designers to provide control of movement and speed in a single low-profile unit.

Joystick offers fingertip control
The new multi-axis JC400 joystick from Penny and Giles Controls has been developed for applications such as fork lift trucks and remote control systems.
They combine precise fingertip control with low profile rocker buttons, allowing system designers to develop very low profile control panel assemblies without sacrificing the functionality of a much larger single axis joystick.
This makes them ideal for applications such as remote control chest packs; operator controls for forklift trucks and off highway vehicles; and broadcasting and lighting control desks.
The JC025 is intended for use where minimum space is available below the panel.
The JC030 has a slightly larger footprint with a protective case surrounding its mechanism.
The absence of microswitches and camshafts means both rockers are maintenance-free throughout their operating life, which is in excess of 5 million cycles.
The JC025 and JC030 are designed to interface with an electronic controller and both have an analogue output proportional to the position of the rocker button (0 to 100%) provided by a high quality conductive plastic potentiometer element.
As an additional safety feature, system designers can specify padding resistors to limit the analogue output signal to between 10% and 90% or 25% and 75% of the supply voltage.
Switched reference signals are provided to operate at ±2.5º from the centre position, allowing the electronic controller to identify the direction in which the rocker is moving.
This feature can also be used to create controller fault detection circuits.
A spring mechanism returns the rocker button to the centre position when released.
An electrical centre tap provides an accurate voltage reference signal for the centre position, or a zero point for a bipolar supply voltage.
The rockers have a current rating of 200mA (resistive load), with a maximum supply of 35 Vdc. Request a free brochure from Penny + Giles ...
