MODRATEC has developed this range of WIT Products (wire-in-tube) to help those who decide to connect devices to their MODRATEC Interlocked Lever Frames using mechanical linkages. Point-wit, Sig-wit, Slot-wit, Link-wit and Crank-wit are mechanisms uniquely designed by MODRATEC.

WIT Products by MODRATEC

For clever and reliable 'wire-in-tube' mechanical control of points and signals, without the traditional headaches.

Rationale

Mechanical control using the wire-in-tube method is not new. But MODRATEC has developed its range of WIT Products with the aim of eliminating the headaches that have traditionally been associated with this form of control.

  • The performance of our WIT Control is not affected by temperature.
  • There is no need for precision adjustment of linkages.
  • It is simple to operate across baseboard joins.
  • It is simple to fix the danger and clear positions of semaphores.
  • It is simple to 'slot' signals.

And the traditional benefits of WIT Control remain.

  • It is very affordable.
  • It is easily understood - you can see what is going on.
  • You have direct control over the speed of operation of points and signals.
  • It is quiet.
  • It is robust.

Data Sheets in PDF Format

-- NEW -- WIT Starter Packs offer an opportunity to try wire-in-tube control. Packs include a Premium non-interlocked Lever Frame Kit and sufficient wire (6m x 1mm, 0.6m x 1.15mm), tube (5m Flex-wit) (quantities doubled for 12-lever pack), clamps and mechanisms for controlling one set of points per lever. Ideal for yard points, or any points on layouts that are not signalled.
