Abstract: For a bi-directional bus topology, a node connection includes two select line connections for a select line of a serial network. The select line is broken at the node connection. A bus direction module configures a first select line connection for an input line and a second select line connection for an output line in response to detecting a selection event. At least a portion of the bus direction module includes one or more of hardware and executable code, the executable code stored on a memory.

Abstract: A switching element (40, 40′) for use in a snap-acting electrical switch (10) has a pair of outer legs (40a, 40b; 40a′, 40b′) and a center leg (40c) extending in substantially the same direction from a junction portion. The outer legs have a semi-annular band portion which blend together at the junction portion and a center leg at one end of the band portion. A mounting portion extends from the other end of the semi-annular band portion and is provided with mounting apertures (40k, 40l) for placement on mounting posts (18, 20) in a warped, stressed condition. A strengthening portion (40n, 40r) is formed in each semi-annular band portion, preferably along the outer portion thereof, i.e., the outer portion being away from the junction portion. An electrical contact (32) is mounted on the distal free end of the center leg for snap-movement between a pair of stationary electrical contacts (28b, 30b).
